Fig. 5From: The camelliagenin from defatted seeds of Camellia oleifera as antibiotic substitute to treat chicken against infection of Escherichia coli and Staphylococcus aureus Activity of mannitol dehydrogenase (a) and content of extracellular DNA (b) in bacterial biofilm affected by the saponin and antibiotics (\( \overline{x}+s \), n = 5). Data were measured respectively by a decrease in the absorbance of reactive mixture at 340 nm and biofilm lysate at 260 nm compared to untreated controls. ∆ 340 nm reflects decrease of mannitol dehydrogenase activity, and ∆ 260 nm reflects decrease of eDNA in biofilm. a, p < 0.01, compared with amoxicillin; b, p < 0.01, compared with the saponin; c, p < 0.01, compared with erythromycin.
